Hey, she needs to rest sometime.
like men, hobbits are the strangest creation because only eru knows their eventual fates. yavannah begged eru for ents to protect trees while aule made a similar entreat for dwarves. elves (and orcs) of course were supposed to earth-bound. and hobbits see elves pretty much the same way men do: “while those (elves) who live on will live with a great weariness and wane, and appear as mere shadows of regret to the younger children who come thereafter. the valar have spoken.”
